Radius Dependent Luminosity Evolution of Blue Galaxies in GOODS-N
J. Melbourne, A. C. Phillips, J. Harker +3
We examine the radius-luminosity (R-L) relation for blue galaxies in the Team Keck Redshift Survey (TKRS) of GOODS-N. We compare with a volume-limited, Sloan Digital Sky Survey sam…
A Photometric and Spectroscopic Search for White Dwarfs in the Open Clusters NGC 6633 and NGC 7063
Kurtis A. Williams, Michael Bolte
We present photometric and spectroscopic studies of the white dwarf (WD) populations in the intermediate-age open clusters NGC 6633 and NGC 7063 as part of the ongoing Lick-Arizona…
Supernovae in Low-Redshift Galaxy Clusters: the Type-Ia Supernova Rate
Keren Sharon, Avishay Gal-Yam, Dan Maoz +3
Supernova (SN) rates are a potentially powerful diagnostic of star formation history (SFH), metal enrichment, and SN physics, particularly in galaxy clusters with their deep, metal…
The Centers of Early-Type Galaxies with HST. VI. Bimodal Central Surface Brightness Profiles
Tod R. Lauer, Karl Gebhardt, S. M. Faber +9
We combine the results from several HST investigations of the central structure of early-type galaxies to generate a large sample of parameterized surface photometry. The studies i…
Mid-infrared Identification of 6 cm Radio Source Counterparts in the Extended Groth Strip
S. P. Willner, A. L. Coil, W. M. Goss +7
A new 6-cm survey of almost 0.6 square degrees to a limit of 0.55-mJy/beam (10-sigma) finds 37 isolated radio sources and 7 radio source pairs (not necessarily physical companions)…
Comparing Dynamical and Photometric Mass Estimates of Low- and High-Redshift Galaxies: Random and Systematic Uncertainties
Arjen van der Wel, Marijn Franx, Stijn Wuyts +4
We determine the importance of redshift-dependent systematic effects in the determination of stellar masses from broad band spectral energy distributions (SEDs), using high quality…
Catalog of Nearby Exoplanets
R. P. Butler, J. T. Wright, G. W. Marcy +8
We present a catalog of nearby exoplanets, available at http://exoplanets.org and ApJ 646, 505 (published version available at the link above). It contains the 172 known low mass c…
Population Synthesis Models for Late Build-Up of the Red Sequence
Justin J. Harker, Ricardo P. Schiavon, Benjamin J. Weiner +1
We present population synthesis models designed to represent the star formation histories of L* red sequence galaxies (RSGs). Earlier work has shown that single-burst stellar popul…
Survey for Galaxies Associated with z~3 Damped Lyman alpha Systems II: Galaxy-Absorber Correlation Functions
Jeff Cooke, Arthur M. Wolfe, Eric Gawiser +1
We use 211 galaxy spectra from our survey for Lyman break galaxies (LBGs) associated with 11 damped Lyman alpha systems (DLAs) to measure the three-dimensional LBG auto-correlation…
The DEEP2 Galaxy Redshift Survey: Clustering of Quasars and Galaxies at z=1
Alison L. Coil, Joseph F. Hennawi, Jeffrey A. Newman +2
We present the clustering of DEEP2 galaxies at 0.7<z<1.4 around quasars identified using both the SDSS and DEEP2 surveys. We measure the two-point cross-correlation of a sample of…
Clustering of i-dropout galaxies at z=6 in GOODS and the UDF
Roderik A. Overzier, Rychard J. Bouwens, Garth D. Illingworth +1
We measured the angular clustering at z~6 from a large sample of i-dropout galaxies (293 with z<27.5 from GOODS and 95 with z<29.0 from the UDF). Our largest and most complete subs…
Temporal Variation in Excited Fe^+ Near a GRB Afterglow
Miroslava Dessauges-Zavadsky, Hsiao-Wen Chen, Jason X. Prochaska +2
Excited Si^+ and Fe^+ species are routinely observed in the host environment of gamma-ray burst (GRB) afterglows, but are not commonly seen in other extragalactic locations. Their…
The Masses of Nuclear Black Holes in Luminous Elliptical Galaxies and Implications for the Space Density of the Most Massive Black Holes
Tod R. Lauer, S. M. Faber, Douglas Richstone +11
Black hole masses predicted from the Mbh-sigma relationship conflict with those predicted from the Mbh-L relationship for the most luminous galaxies, such as brightest cluster gala…
Star Formation History of the Hubble Ultra Deep Field: Comparison with the HDFN
Rodger I. Thompson, Daniel Eisenstein, Xiaohui Fan +3
We use the NICMOS Treasury and ACS HUDF images to measure the extinction corrected star formation history for 4681 galaxies in the region common to both images utilizing the star f…
A Hot DQ White Dwarf in the Open Star Cluster M35
Kurtis A. Williams, James Liebert, Michael Bolte +1
We report the discovery of a hot DQ white dwarf, NGC 2168:LAWDS 28, that is a likely member of the 150-Myr old cluster NGC 2168 (Messier 35). The spectrum of the white dwarf is dom…
Quasars Probing Quasars I: Optically Thick Absorbers Near Luminous Quasars
Joseph F. Hennawi, Jason X. Prochaska, Scott Burles +11
With close pairs of quasars at different redshifts, a background quasar sightline can be used to study a foreground quasar's environment in absorption. We search 149 moderate resol…
Andromeda X, A New Dwarf Spheroidal Satellite of M31: Photometry
Daniel B. Zucker, Alexei Y. Kniazev, David Martinez-Delgado +17
We report the discovery of Andromeda X, a new dwarf spheroidal satellite of M31, based on stellar photometry from the Sloan Digital Sky Survey (SDSS). Using follow-up imaging data…
Weak-Lensing Detection at z~1.3: Measurement of the Two Lynx Clusters with Advanced Camera for Surveys
M. J. Jee, R. L. White, H. C. Ford +4
(Abridged) We present a HST/ACS weak-lensing study of RX J0849+4452 and RX J0848+4453, the two most distant (at z=1.26 and z=1.27, respectively) clusters yet measured with weak-len…
